EGG-TESTER.

Specification of Letters Patent.

Patented Sept. 23, 1913.

Application filed October 30, 1912. Serial No. 728,553.

To all whom t may concern Be it known that I, 'GEORGE THOMAS Cmrrs, ofthe city of Toronto, in the county of York, in the Province of Ontario,Canada, have invented certain new and useful Imprm'ements inEgg-Testers, .of which the following is the specification.

Myinvention relates to improvements 1n egg testers, and the object ofthe invention is to devise a simple device in which the egg isilluminated and reflected in a suitable mirror so that both sides of theegg will be simultaneously under observation and 1n which the power ofthe reflector designed to throw the light against the egg is increasedand by which the eyes of the operator will be shielded while testing theeggs and it consists essentially of a casing provided with a suitablelight at the bottom thereof and having an opening at the top and anopening 1n the side and a reflecting mirror compr1smg two leavesconnected together at their inner ends andpivoted at the point ofconnectien to the wall of the casing, so that they will alternatelycover the top and side opening of the casing as hereinafter moreparticularly explained.

Figure 1, is a general perspective view of my device showing the egg inposition. Fig. 2, is a vertical section through Fig. 1. Fig. 3, is aperspective view' of my device as shown when the side opening isemployed.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is a casing preferably and substantially oval in vertical section andhaving flat ends A and A2, the lower end being formed into a stand A3connected to a base board A4. The casing A is also preferably dividedhorizontally so as to form two halves A5 and A, the upper half A5 beingprovided with a slight enlargement A7 at the lower edge forming a grooveAB into which the upper end of the lower portion A is inserted.

B is an incandescent light secured in any suitable manner to the baseboard A4 and' provided with the usual connections extending 'through theopening AD in the side of the base A3.

A10 is an opening in the upper flat' end of the casing A and A11 is anopening in the side of the casing in proximity to the top thereof.

C is a double reflector comprising the leaf C' and the leaf C2 havinginturned lips C3.

r1`he reflector C is pivotally connected at C* to the wall of. thecasing A directly above the opening All.

In testing the eggs ordinarily where econonly of time is essential I usemy tester as shown in Fig. 3, the leaf C2 of the reflector being turnedupwardly and the opening A10 covered by the reflecting leaf C. The raysof the light from the incandescent bulb pass through the opening A andthe eggs are passed successively by the operator in front of theopening, the upturned leaf C2 serving to protect the eyes of theoperator by reflecting the upwardly extending rays of the light down.

lVhen'it is desired to test the eggs with great care and where economyof time is not essential I use the tester as shown in 2 Figs. l and 2.The egg is placed in the hole A1", the rays of light passing upwardlythrough the egg, one side of the egg being directly under theobservation of the operalor and the other side being reflected in themirror leaf C. By this means both sides of the egg are simultaneously inview of the operator.

To provide sufficient ventilation in the interior of the casing the lipC3 prevents the mirror leaf C2 from entirely closing the opening A,thereby allowing the heated air to pass between the outside wall of thecasing and the leaf C2.

D is a tapered reflector provided with corrugations extending from thetop to the bottom of the reflector. The reflector D is placed within thecasing A, so as to surround the incandescent light B as shown in Fig. 2of the drawings. By this means a maximum reflecting surface is providedthereby increasing the transparency of the egg subjected to the rays oflight from the bulb.

From this description it Will be seen that I have devised a very simpledevice wherein both sides of the egg may be under the observation oftheoperatorand in which a maximum reflecting surface is provided for thelight illuminating the egg'and in which sufficient ventilation isprovided and the eyes 'of the operator protected during the operation oftesting.

What I claim as my invention is:

1. An egg testing device comprising a casing provided with a suitablesource of artificial light in the interior thereof and having an openingat the upper end thereof in which the egg is designed to rest and enopening in the side, and a reecting mirror pivotally mounted betweensaid openings as and for the purpose speciied.

2. An egg testing device comprising a casin provided with e suitablesource ot artificie. light in the interior thereof and hevmg en o eninget the top, and an opening i5 alternately/.close the openings in theseme es end for the purpose specified.

3. An egg testing device comprising n casing provided with e suitablesource of erti- Leveren icil light in the interior thereof and having enopening in the side in proximity to the top thereof, and ai reflectingshield extending outwardly from the casing over such o ening,' as .andfor the purpose speciie 4. An egg testing device comprising a. casingprovided with a suitable source of artificial light in the interiorthereof, and having an opening at the top, and an opening in.

the side in proximity to the top, and means for simultaneously coveringone of -sa-id t openings and opening the other.
